IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 36,644, dated October 14, 1862.

sponding parts in the two figures.

The object ofthis invention is to obtain a jointed or flexible harrow of simple construction, and which will be strong and durable, with its teeth well braced, and so arranged or fitted in or to the barrow as not only to be permanently securedin position,butalso made to serve as a means tofirmly connect the framing of the harrow together, or keep the parts thereof in a proper relative position with each other.

To enable those skilled in the art to fully understand and construct my invention,.I will proceed to describe it.

The frame of the harrow is constructedbf wrought-metal bars a a, of fiat form, and so placed or disposed as to cross each other at right angles, as shown clearly in Fig. 1.

I design to construct theharrow of two equal parts, A A, and connect the same together by means of hinges orjoint-s formed by bending the contiguous ends of the bars a in avertical position, having them lap a certain distance, as shown at to, and perforated to admit of a rod or shaft, B, passing through them, on which the bars a may work or play freely. By this means simple and durable joints or hinges are obtained, the ends of the rod or shaft B being headed to prevent its casual withdrawal from the bars a.

C represents the teeth of the barrow. These are of quadrilateraltorm, pointed at theirlower ends,and pass through holes made in the bars a a, where they cross each other. The teeth are fitted in metal sockets D at their upper parts above the sac. These sockets are of oblong form, and provided at their centers witha head, I), which serves to firmly support the teeth. -The teeth also pass through similar sockets, E, which are underneath the bars a, a, and are precisely similar in construction to the sockets D, being provided with heads a, which also serve to support the teeth C. The sockets D are in line with the sockets E, and they have an angular or oblique position with the bars cut, as shown in Fig. 1, theends of the sockets projecting over or beyond the angles formed by the intersection of thebars a a. The upper and lower sockets, D E, are connected together by screws or screw-bolts d, which fit snugly in the angles of the bars and serve as bracesfor the same to retain them in proper position or preventany lateral workin g. The sockets also serve as clamps to keep the surfaces of the bars a a, where they cross each other, in close contact.

The clamps may be of wrought or cast iron.

Malleable cast-iron would answer a good purpose. I do not, however, confine myself to anyparticularmatcrial. 1fneeessary,theteeth may be secured in the upper sockets, D, by means of pins passing horizontally into the upper sockets or heads thereof and into the teeth, and also into the lower sockets, E.

By constructing the barrow in this way it is rendered extremely strong, light, and durable, and may be manufactured at a moderate cost, there being but little for the mechanic to do, except the mere assembling of the parts and adjusting them together, as the parts may be obtained or be all furnished ready to be secured together.

The bars a a may be of any desired thickness and width, according to the size of the barrow.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The bars a a, arranged or disposed so as to cross each other at right angles, in combina' tion with the teeth C and sockets D E, the teeth passing through the sockets and bars, and the sockets adjusted to the barsand made to clamp the same by means of the screws or bolts d, which fitin the angles of the bars,subs'tantially as and for the purpose herein set forth.
